This is obviously an error in the ncdf4 package or the underlying NetCDF library. I cannot reproduce it on my development machine. I notice that you are working on a 32-bit PPC system, do you get the same error on a 64-bit system?

Please post package versions and NetCDF library version (type ncdump at a terminal - I get version 4.9.2 on my machine) if you want me to dig a little deeper.

Thank you for responding!

I could check on roughly identical system (macOS 10.6) for i368 and x86_64, which would help to understand whether the error is caused by bitness or endianness (or SDK). Probably tomorrow, since right now I am away from Intel hardware.

By the way, maybe it was just never fixed: https://github.com/Unidata/netcdf-c/issues/1481

I looked online as well and this indeed appears to be an issue in the NetCDF library. You may want to report the issue to David Pierce, the developer of ncdf4.

@pvanlaake Thank you very much! I close this issue now, since the bug is in the dependency, not here.
